Abstract

During coal production, a significant amount of fine coal dust is generated. Utilizing these high-ash coals is of great importance for the national economy. This study aims to recover the slime of the coal washing plant located in the Kütahya-Tuncbilek region by flotation. The experimental parameters studied include the collector dosage, dispersant dosage, frother dosage, flotation time, air flow rate, and solid ratio. Flotation performance was evaluated by determining the ash, calorific value, sulfur, volatile matter, fixed carbon, and combustible recovery values of the products obtained at the end of the experiment. As a result of the experimental studies, the highest combustible matter recovery value was obtained using 2000 g/t sodium silicate, 2000 g/t diesel oil, and 100 g/t MIBC with a solid ratio of 10%, a flotation time of 4 minutes, and an air flow rate of 4 L/min. Thus, marketable coal was produced with 6312 kcal/kg calorific value, 0.95% sulfur, and 22.4% ash content.

Abstract

Kömür üretimi sırasında yüksek miktarlarda ince boyutlu toz kömür ortaya çıkmaktadır. Yüksek kül içerikli bu kömürlerin değerlendirilmesi ülke ekonomisi açısından büyük önem taşımaktadır. Bu çalışmada Kütahya-Tunçbilek bölgesinde bulunan lavvar tesisindeki tikiner altı şlamlı malzemenin flotasyonla zenginleştirilerek ekonomiye kazandırılması amaçlanmıştır. Toplayıcı miktarı, köpürtücü miktarı, flotasyon süresi, hava akış hızı ve katı oranı çalışılan deneysel parametrelerdir. Flotasyon performansı, deney sonunda elde edilen ürünler üzerinde kül, kalori, kükürt, uçucu madde, sabit karbon ve verim değerleri belirlenerek değerlendirilmiştir. Gerçekleştirilen deneysel çalışmalar sonucunda, 4 L/d hava akış hızında, 4 dakika flotasyon süresinde, %10 katı oranı, 2000 g/t Sodyum silikat, 2000 g/t mazot ve 100 g/t MIBC kullanılarak gerçekleştirilen en yüksek verim değerine sahip deney sonucu ile 6312 KCal/Kg ısıl değere sahip %0.95 kükürt ve %22.4 kül içerikli satılabilir kömür elde edilmiştir.
